As Trump Travels To Summit, Congress May Be Reasserting Itself On Overseas Affairs

Corker even spoke of holding up arms sales to the region that the Trump administration has trumpeted as a success story.

That question begs another: What is the role of the Congress in foreign policy supposed to be in the first place?
The foreign policy thrust of the White House is itself a struggle between more traditional Republicans and advocates of “America First” nationalism.
Yet in fact, the president makes and executes foreign policy not by himself but in a complex partnership with Congress.
